Collectively, these findings reveal a previously unknown mechanism of action of ecteinascidins that merits further investigation for potential clinical applications in the treatment of MPM, as new first line treatment in monotherapy or in association with immunotherapy.
Background - Ecubectedin (PM14) is a novel transcriptional inhibitor related to ecteinascidins family...In mice bearing MDA-MB-231, H526 and 22Rv1 tumors, complete tumor remissions were seen in 1/10 (lasting 103 days), 9/10 (lasting 220 days) and 7/10 (lasting 13 days) ecubectedin-treated animals, respectively.Conclusions - Ecubectedin is a novel transcriptional inhibitor that displays potent antiproliferative activity in different human solid cancer models in vitro and in vivo. The drug is currently in clinical development in Phase II trials.
